What does copy.copy of an enumeration value do?  What happens if you
have a list with some enumeration values inside, and you make a
deepcopy of it?  What happens if you pickle an enum, then unpickle the
pickle and compare what comes out to the other enum?

All in all, comparing by object identity doesn't sound too good.
Maybe you want to have the enum contain its own name internally, and
do a string comparison.
